WebThe first qualitative information on the stability of platinum(II)–olefin complexes, obtained in 1936, 1306 showed that the coordinating ability of olefins decreased with increasing substitution of the olefinic double bond in the order C 2 H 4 > PhCH CH 2 > Ph 2 C CH 2 ≈ Ph(Me)C CH 2.Since then the results of a number of workers have shown that the … WebStereospecific Catalytic Polymerization of α-Olefins α-olefins are often polymerized in the presence of stereospecific catalysts such as metallocenes or Ziegler-Natta catalysts. 1 These catalysts are able to restict the addition of monomer molecules to a specific regular orientation ().In the case of isotactic orientation, all alkyl groups are positioned at the …
